Digital assistant processing of stacked data structures

ABSTRACT

Processing stacked data structures is provided. A system receives an input audio signal detected by a sensor of a local computing device, identifies an acoustic signature, and identifies an account corresponding to the signature. The system establishes a session and a profile stack data structure including a first profile layer having policies configured by a third-party device. The system pushes, to the profile stack data structure, a second profile layer retrieved from the account. The system parses the input audio signal to identify a request and a trigger keyword. The system generates, based on the trigger keyword and the second profile layer, a first action data structure compatible with the first profile layer. The system provides the first action data structure for execution. The system disassembles the profile stack data structure to remove the first profile layer or the second profile layer from the profile stack data structure.

DETAILED DESCRIPTION

Following below are more detailed descriptions of various conceptsrelated to, and implementations of, methods, apparatuses, and systems ofrouting packetized actions via a computer network. The various conceptsintroduced above and discussed in greater detail below may beimplemented in any of numerous ways.

The present disclosure is generally directed to processing stacked datastructures to operate and improve the efficiency of a digital assistantin a public location. A data processing system can perform speakerrecognition to identify an electronic account, and then push a profileassociated with the speaker to a profile stack data structure thatincludes a first layer having a baseline profile established by athird-party entity associated with the public location. The dataprocessing system can disassemble the profile stack data structureresponsive to a trigger event, thereby maintaining security and reducingerroneous remote procedure calls.

The present solution can reduce resource consumption, processorutilization, battery consumption, bandwidth utilization, size of anaudio file, or amount of time consumed by a speaker by parsingvoice-based instructions from an end user, identifying an acousticsignature, selecting a corresponding profile, pushing the profile to aprofile stack comprising a default profile in a first layer,constructing an action data structure using the selected profile,determining whether the action data structure complies with the defaultprofile, routing the action data structure to a corresponding device,and then disassembling the profile stack responsive to a trigger event.

Systems and methods of the present solution can configure a digitalassistant for use in a public setting, such as a hotel room, or to allowguests to sign into a digital assistant for temporary use (e.g., 10minutes, 30 minutes, 1 hour, 2 hours, 24 hours, 48 hours, 72 hours). Thesolution can allow the digital assistant to intelligently engage anddisengage from an account by reverting back to a previous configurationand erasing or protecting all session information. The digital assistantcan intelligently engage by further establishing sessions or links withany third-party devices or interfaces. The digital assistant can providesecure authentication mechanisms to help ensure the correct device isutilized for a service, such as showing a quick response code, opticalcode, barcode, or other visual or acoustic signal that can providefingerprinting. The solution can disengage by resetting the digitalassistant to factory settings, automatically triggering a disengagement,and providing redundant mechanisms to ensure proper disengagement. Thesolution can also allow for customization of the digital assistant ordigital content provided by the digital assistant. For example, digitalcomponents for the hotel providing the digital assistant can be moreheavily weighted to provide branding for the hotel. Also, digitalcomponents can be provided for the digital assistant if the user doesn'talready have a digital assistant.

FIG. 1 illustrates an example system 100 to process a profile stack. Thesystem 100 can include content selection infrastructure. The system 100can include a data processing system 102.

The network 105 can include computer networks such as the Internet,local, wide, metro, or other area networks, intranets, satellitenetworks, and other communication networks such as voice or data mobiletelephone networks. The network 105 can be used to access informationresources such as web pages, web sites, domain names, or uniformresource locators that can be presented, output, rendered, or displayedon at least one local computing device 104, such as a laptop, desktop,tablet, digital assistant device, smart phone, portable computers, orspeaker. For example, via the network 105 a user of the local computingdevice 104 can access information or data provided by a content provider106. The computing device 104 may or may not include a display; forexample, the computing device may include limited types of userinterfaces, such as a microphone and speaker. In some cases, the primaryuser interface of the computing device 104 may be a microphone andspeaker, or voice interface.

The local computing device 104 can refer to a computing device or clientdevice that is located at a public setting, such as a public location202, or a private setting, such as the private location 402. The termlocal can refer to the computing device being located where a user caninteract with the computing device using voice input or other input. Thelocal computing device can be located remote from a remote server, suchas a data processing system 102. Thus, the local computing device 104can be positioned in a hotel room, mall, cubicle, or other building orabode at which a user can interact with the local computing device 104using voice input, whereas the data processing system 102 can be locatedremotely in a data center, for example.

The network 105 can be used by thedata processing system 102 to access information resources such as webpages, web sites, domain names, or uniform resource locators that can bepresented, output, rendered, or displayed by the local client computingdevice 104. For example, via the network 105 a user of the local clientcomputing device 104 can access information or data provided by thecontent provider computing device 106 or the service provider computingdevice 108.

The network 105 may be any type or form of network and may include anyof the following: a point-to-point network, a broadcast network, a widearea network, a local area network, a telecommunications network, a datacommunication network, a computer network, an ATM (Asynchronous TransferMode) network, a SONET (Synchronous Optical Network) network, a SDH(Synchronous Digital Hierarchy) network, a wireless network and awireline network. The network 105 may include a wireless link, such asan infrared channel or satellite band. The topology of the network 105may include a bus, star, or ring network topology. The network mayinclude mobile telephone networks using any protocol or protocols usedto communicate among mobile devices, including advanced mobile phoneprotocol (“AMPS”), time division multiple access (“TDMA”), code-divisionmultiple access (“CDMA”), global system for mobile communication(“GSM”), general packet radio services (“GPRS”) or universal mobiletelecommunications system (“UMTS”).

Servers in the machine farm can be stored in high-density rack systems,along with associated storage systems, and located in an enterprise datacenter. For example, consolidating the servers in this way may improvesystem manageability, data security, the physical security of thesystem, and system performance by locating servers and high performancestorage systems on localized high performance networks. Centralizationof all or some of the data processing system 102 components, includingservers and storage systems, and coupling them with advanced systemmanagement tools allows more efficient use of server resources, whichsaves power and processing requirements and reduces bandwidth usage.

The system 100 can include, access, or otherwise interact with at leastone third-party device 146. The third-party device 146 can include atleast one logic device such as a computing device having a processor tocommunicate via the network 105, for example with the computing device104, the data processing system 102, or the content provider 106.

A user of a local computing device 104 or mobile computing device144 can affirmatively authorize the data processing system 102 to obtainnetwork activity information corresponding to the local computing device104 or mobile computing device 144. For example, the data processingsystem 102 can prompt the user of the computing device 104 for consentto obtain one or more types of network activity information. Theidentity of the user of the mobile computing device 144 or localcomputing device 104 can remain anonymous and the computing devices 104or 144 can be associated with a unique identifier (e.g., a uniqueidentifier for the user or the computing device provided by the dataprocessing system or a user of the computing device). The dataprocessing system can associate each observation with a correspondingunique identifier.

A content provider 106 can establish an electronic content campaign. Theelectronic content campaign can be stored as content data 130 in datarepository 124. An electronic content campaign can refer to one or morecontent groups that correspond to a common theme. A content campaign caninclude a hierarchical data structure that includes content groups,digital component data objects, and content selection criteria. Tocreate a content campaign, content provider 106 can specify values forcampaign level parameters of the content campaign. The campaign levelparameters can include, for example, a campaign name, a preferredcontent network for placing digital component objects, a value ofresources to be used for the content campaign, start and end dates forthe content campaign, a duration for the content campaign, a schedulefor digital component object placements, language, geographicallocations, type of computing devices on which to provide digitalcomponent objects. In some cases, an impression can refer to when adigital component object is fetched from its source (e.g., dataprocessing system 102 or content provider 106), and is countable. Insome cases, due to the possibility of click fraud, robotic activity canbe filtered and excluded, as an impression. Thus, in some cases, animpression can refer to a measurement of responses from a Web server toa page request from a browser, which is filtered from robotic activityand error codes, and is recorded at a point as close as possible toopportunity to render the digital component object for display on thecomputing device 104. In some cases, an impression can refer to aviewable or audible impression; e.g., the digital component object is atleast partially (e.g., 20%, 30%, 30%, 40%, 50%, 60%, 70%, or more)viewable on a display device of the local client computing device 104,or audible via a speaker 136 of the computing device 104. A click orselection can refer to a user interaction with the digital componentobject, such as a voice response to an audible impression, amouse-click, touch interaction, gesture, shake, audio interaction, orkeyboard click. A conversion can refer to a user taking a desired actionwith respect to the digital component objection; e.g., purchasing aproduct or service, completing a survey, visiting a physical storecorresponding to the digital component, or completing an electronictransaction.

The content provider 106 can further establish one or more contentgroups for a content campaign. A content group includes one or moredigital component objects and corresponding content selection criteria,such as keywords, words, terms, phrases, geographic locations, type ofcomputing device, time of day, interest, topic, or vertical. Contentgroups under the same content campaign can share the same campaign levelparameters, but may have tailored specifications for particular contentgroup level parameters, such as keywords, negative keywords (e.g., thatblock placement of the digital component in the presence of the negativekeyword on main content), bids for keywords, or parameters associatedwith the bid or content campaign.

To create a new content group, the content provider can provide valuesfor the content group level parameters of the content group. The contentgroup level parameters include, for example, a content group name orcontent group theme, and bids for different content placementopportunities (e.g., automatic placement or managed placement) oroutcomes (e.g., clicks, impressions, or conversions). A content groupname or content group theme can be one or more terms that the contentprovider 106 can use to capture a topic or subject matter for whichdigital component objects of the content group is to be selected fordisplay. For example, a car dealership can create a different contentgroup for each brand of vehicle it carries, and may further create adifferent content group for each model of vehicle it carries. Examplesof the content group themes that the car dealership can use include, forexample, “Make A sports car” “Make B sports car,” “Make C sedan,” “MakeC truck,” “Make C hybrid,” or “Make D hybrid.” An example contentcampaign theme can be “hybrid” and include content groups for both “MakeC hybrid” and “Make D hybrid”, for example.

The content provider 106 can provide one or more keywords and digitalcomponent objects to each content group. Keywords can include terms thatare relevant to the product or services of associated with or identifiedby the digital component objects. A keyword can include one or moreterms or phrases. For example, the car dealership can include “sportscar,” “V-6 engine,” “four-wheel drive,” “fuel efficiency,” as keywordsfor a content group or content campaign. In some cases, negativekeywords can be specified by the content provider to avoid, prevent,block, or disable content placement on certain terms or keywords. Thecontent provider can specify a type of matching, such as exact match,phrase match, or broad match, used to select digital component objects.

The content provider 106 can provide one or more keywords to be used bythe data processing system 102 to select a digital component objectprovided by the content provider 106. The content provider 106 canidentify one or more keywords to bid on, and further provide bid amountsfor various keywords. The content provider 106 can provide additionalcontent selection criteria to be used by the data processing system 102to select digital component objects. Multiple content providers 106 canbid on the same or different keywords, and the data processing system102 can run a content selection process or ad auction responsive toreceiving an indication of a keyword of an electronic message.

The content provider 106 can provide one or more digital componentobjects for selection by the data processing system 102. The dataprocessing system 102 (e.g., via content selector component 118) canselect the digital component objects when a content placementopportunity becomes available that matches the resource allocation,content schedule, maximum bids, keywords, and other selection criteriaspecified for the content group. Different types of digital componentobjects can be included in a content group, such as a voice digitalcomponent, audio digital component, a text digital component, an imagedigital component, video digital component, multimedia digitalcomponent, or digital component link. A digital component object (ordigital component) can include, for example, a content item, an onlinedocument, audio, images, video, multimedia content, or sponsoredcontent. Upon selecting a digital component, the data processing system102 can transmit the digital component object for rendering on acomputing device 104 or display device of the computing device 104.Rendering can include displaying the digital component on a displaydevice, or playing the digital component via a speaker of the computingdevice 104. The data processing system 102 can provide instructions to acomputing device 104 to render the digital component object. The dataprocessing system 102 can instruct the computing device 104, or an audiodriver 138 of the computing device 104, to generate audio signals oracoustic waves.

The data processing system 102 can include an interface component 110designed, configured, constructed, or operational to receive andtransmit information using, for example, data packets. The interface 110can receive and transmit information using one or more protocols, suchas a network protocol. The interface 110 can include a hardwareinterface, software interface, wired interface, or wireless interface.The interface 110 can facilitate translating or formatting data from oneformat to another format. For example, the interface 110 can include anapplication programming interface that includes definitions forcommunicating between various components, such as software components.The interface 110 can communicate with one or more of the localcomputing device 104, content provider device 106, third-party device146, or mobile computing device 144 via network 105.

The data processing system 102 can interface with an application, scriptor program installed at the local client computing device 104, such asan app to communicate input audio signals to the interface 110 of thedata processing system 102 and to drive components of the local clientcomputing device to render output audio signals. The data processingsystem 102 can receive data packets or other signal that includes oridentifies an audio input signal.

The data processing system 102 can include a speaker recognitioncomponent 120 that is designed, constructed and operational to receivean audio input signal detected by the local computing device 104,identify an acoustic signature, and identify an electronic accountcorresponding to the acoustic signature. The speaker recognitioncomponent 120 can receive, via interface 110, data packets that includean input audio signal detected by a sensor 134 or transducer 136 of thelocal computing device 104. The speaker recognition component 120 canidentify an acoustic signature from the input audio signal. The speakerrecognition component 120 can identify, based on a lookup in the datarepository 124, an electronic account corresponding to the acousticsignature.

The speaker recognition component 120 can receive data packets having apayload carrying the input audio signals. The speaker recognitioncomponent 120 can perform a pre-filtering or pre-processing on the inputaudio signal to remove certain frequencies of audio. The pre-filteringcan include filters such as a low-pass filter, high-pass filter or abandpass filter. The filters can be applied in the frequency domain. Thefilters can be applied using a digital signal processing technique. Thefilter can be configured to keep frequencies that correspond to a humanvoice or human speech, while eliminating frequencies that fall outsidethe typical frequencies of human speech. For example, a bandpass filtercan be configured to remove frequencies bellow a first threshold (e.g.,70 Hz, 75 Hz, 80 Hz, 85 Hz, 90 Hz, 95 Hz, 100 Hz, or 105 Hz) and above asecond threshold (e.g., 200 Hz, 205 Hz, 210 Hz, 225 Hz, 235 Hz, 245 Hz,or 255 Hz). Applying a bandpass filter can reduce computing resourceutilization in downstream processing. In some cases, the pre-processor140 on the local computing device 104 can apply the bandpass filterprior to transmitting the input audio signal to the data processingsystem 102, thereby reducing network bandwidth utilization. However,based on the computing resources available to the local computing device104, it may be more efficient to provide the input audio signal to thedata processing system 102 to allow the data processing system 102 toperform the filtering.

The speaker recognition component 120 can apply additionalpre-processing or pre-filtering techniques to facilitate identifying theelectronic account corresponding to the speaker. For example, thespeaker recognition component 120 can apply noise reduction techniquesto reduce ambient noise levels that can interfere with speakerrecognition. Noise reduction techniques can improve accuracy and speedof speaker recognition, thereby improving the performance of the dataprocessing system 102 in identifying the electronic account.

The speaker recognition component 120 can access signatures 132 storedin the data repository 124. The speaker recognition component 120 cananalyze the filtered input audio signal to identify signature, and usethe signature to identify an electronic account. Thus, the speakerrecognition component 120 can perform speaker recognition or voicerecognition to identify an electronic account corresponding to thesignature of the input audio signal.

The speaker recognition component 120 can be configured with one or morespeaker recognition techniques, such as pattern recognition. The speakerrecognition component 120 can be configured with a text-independentspeaker recognition process. In a text-independent speaker recognitionprocess, the text used to establish the electronic account can bedifferent from the text used to later recognize the speaker.

For example, the speaker recognition component 120 can identify acousticfeatures in the input audio signal that differ between input speechsources. The acoustic features can reflect physical or learned patternsthat can correspond to a unique input speech source. Acoustic featurescan include, for example, voice pitch or speaking style. Techniques usedto identify, process and store signatures can include frequencyestimation (e.g., instantaneous fundamental frequency, or discreteenergy separation algorithm), hidden Markov models (e.g., a stochasticmodel used to model randomly changing systems where the future stateddepends on the current state, and in which the system being modeled hasunobserved states), Gaussian mixture models (e.g., a parametricprobability density function represented as a weighted sum of Gaussiancomponent densities), pattern matching algorithms, neural networks,matrix representation, Vector Quantization (e.g., a quantizationtechnique from signal processing that allows the modeling of probabilitydensity functions by the distribution of prototype vectors), or decisiontrees. Additional techniques can include anti-speaker techniques, suchas cohort models, and world models. The speaker recognition component120 can be configured with a machine learning model to facilitatepattern recognition or adapt to speaker characteristics.

Upon identifying the acoustic signature in the input audio signal, thespeaker recognition component 120 can perform a lookup in the datarepository 124 or signature data structure 132. The signatures stored inthe signature data structure 132 can map to an identifier of anelectronic account. The speaker recognition component 120 can performthe lookup in the signature data structure 132 using the signatureidentified in the input audio signal to retrieve the electronic accountcorresponding to the signature of the input audio.

In some cases, the speaker recognition component 120 can determine,based on the lookup, an absence of the electronic account correspondingto the acoustic signature. For example, the signature may not be storedin the signature data structure 132 or an electronic account for thesignature may not yet have been established. The lookup may return anull value or empty set. Responsive to determining the absence of thesignature or an electronic account, the speaker recognition component120 can create the electronic account in the data repository. Thespeaker recognition component 120 can update the signature datastructure 132 to include a new signature constructed from the inputaudio signal and a corresponding electronic account. The speakerrecognition component 120 can map the electronic account to the newacoustic signature.

The data processing system 102 can include, interface with or otherwiseaccess a stacking engine component 114 designed, constructed andoperation to establish a session and combine one or more profiles foruse during the session. The stacking engine component 114 can receivethe indication of the electronic account from the speaker recognitioncomponent 120. The stacking engine component 114 can retrieveinformation associated with the electronic account from the signaturesand accounts data structure 132. The electronic account can storeinformation that facilitates processing input audio queries andgenerating responses. The electronic account can include a profile thatcorresponds to the speaker that provided the input audio signal. Theprofile can include labels, rules, preferences, identifiers,subscriptions, account settings, or device configuration settings. Theprofile can include configurations information to interact with otherremote devices, such as a mobile computing device 144 associated withthe electronic account, or other networked devices associated with theelectronic account.

For example, the electronic account can include a label for a networkeddevice, such as a thermostat configured to interface with network 105.The thermostat can be located at a first location (e.g., residence)associated with the speaker corresponding to the electronic account. Inthe profile, the thermostat can have the label “living room” thermostat.When the data processing system 102 receives an input query “what is thetemperature in the living room” or “set the temperature in the livingroom to 70 degrees”, the data processing system 102 can determine, viathe profile, that the electronic account is linked to a thermostat thathas a label “living room”, and then provide the label to the directaction API 116 to generate an action data structure corresponding to thethermostat labeled “living room”.

However, the local computing device 104 that detects the input audiosignal may not be located at the first location. Rather, the localcomputing device 104 can be located at a second location physically andgeographically separate from the first location. The second location canbe a location managed, administered, under the control of, or otherwisemaintained by a third-party entity associated with the thirdparty-device. The second location can be an unsecured location, a publiclocation, or a temporary location, such as a hotel room, meeting room,conference room, retail store, rental vehicle, guest room, hostile, ordormitory.

The third-party device 146 that maintains the public location orunsecured location can establish and maintain the local computing device104. The third-party device 146 can establish a baseline or defaultprofile for the local computing device 104. The third-party device 146can provide a first profile. The first profile can be a baselineprofile, default profile, or third-party profile. The third-party device146 can establish the first profile. The first profile can include oneor more policies or rules established by the third-party device 146. Forexample, the third-party device 146 can provide policies, rules orconfiguration settings that block or prevent certain types of activitiesor actions, while more heavily weighting other types of activities oractions. The policy can be stored in the first profile.

The first profile can include labels for internet connected devices. Thelabels in the first profile can be established or provided by thethird-party device 146. For example, the labels can correspond tointernet connected devices (e.g., internet connected thermostat,internet connected light source, internet connected smoke alarm,internet connected appliance, internet connected display, internetconnected television, or internet connected speaker). The labels forthese internet connected devices can be provided by the third-partyentity. For example, the label can be “hotel thermostat” or “Brand AHotel thermostat”.

The third-party device 146 can provide the first profile to the dataprocessing system 102 to cause the data processing system 102 to pushthe first profile to a profile stack initiated for a session associatedwith the local computing device 104. The stacking engine component 114can store, place, or stack the first profile in a first profile layer inthe profile stack that is established for the session. The profile stackdata structure can include the first profile layer having one or morepolicies configured by a device of a third-party entity (e.g.,third-party device 146).

The stacking engine component 114 can establish, responsive toidentification of the electronic account, a session. The session canrefer to communication session, digital assistant session, direct actionsession, content selection session, digital component selection session,or profile session. A session can have a duration. The session cancontinue until a termination event or condition occurs. The terminationevent can cause the session to end. The state of the session can bestored upon termination. A profile in the profile stack can be updatedupon termination of the session.

The stacking engine component 114 can establish a profile stack datastructure for use in the session. The stacking engine component 114 caninitialize the profile stack data structure to include the first profileprovided by the third-party device 146.

The stacking engine component 114 can push the first profile (e.g., adefault profile for the local computing device 104) to a first layer inthe profile stack. For example, the stacking engine component 114 candetermine that the default profile is provided by the third-party device146 that is associated with the same third-party that maintains, owns,manage, or administers the local computing device 104.

The stacking engine component 114 can then retrieve a second profilecorresponding to the electronic account and signature. The stackingengine component 114 can push the second profile to the profile datastructure. For example, the first profile layer can include the firstprofile, and the second profile layer can include the second profile.

The stacking engine component 114 can provide the profile stackcomprising the first profile layer and the second profile layer to oneor more components of the data processing system 102 for furtherprocessing. In some cases, the stacking engine component 114 can meld,merge or otherwise combine the first profile layer and the secondprofile layer to create a single profile layer. In some cases, thestacking engine component 114 can provide the profile stack with the twoprofile layers to the direction action API 116 or content selectorcomponent 118 for further processing.

Establishing the profile stack data structure with the second profilelayer and the first profile layer can include engaging with one or moreinternet connected devices, sessions, interfaces, or third-party devicesassociated or indicated in the first profile layer and the secondprofile layer. For example, the first profile layer can include internetconnected devices 204, 206, 208, 210, and 212 depicted in the securedpublic setting 202 of FIG. 2, and the second profile layer can includeinternet connected devices 204, 206, 208, 210, and 212 depicted in theprivate setting 402 in FIG. 4. The internet connected devices in thepublic setting 202 can have different identifiers as compared to theinternet connect devices in the private setting 402. The data processingsystem 102, upon establishing the profile stack data structure, canping, poll, or otherwise query each of the internet connected devices toperform a status check or enter a readiness state.

The data processing system 102 can use the profile stack to processqueries or actions received via input audio signals from the localcomputing device 104. The data processing system 102 can use the NLPcomponent 112 to identify the query in the input audio signal, and thenthe direct action API 116 can use the profile stack to process the inputquery to generate an action data structure that is in accordance with,and compliant with, the profile stack.

For example, the data processing system 102 can execute or run the NLPcomponent 112 to receive or obtain the audio signal and parse the audiosignal. For example, the NLP component 112 can provide for interactionsbetween a human and a computer. The NLP component 112 can be configuredwith techniques for understanding natural language and allowing the dataprocessing system 102 to derive meaning from human or natural languageinput. The NLP component 112 can include or be configured with techniquebased on machine learning, such as statistical machine learning. The NLPcomponent 112 can utilize decision trees, statistical models, orprobabilistic models to parse the input audio signal. The NLP component112 can perform, for example, functions such as named entity recognition(e.g., given a stream of text, determine which items in the text map toproper names, such as people or places, and what the type of each suchname is, such as person, location, or organization), natural languagegeneration (e.g., convert information from computer databases orsemantic intents into understandable human language), natural languageunderstanding (e.g., convert text into more formal representations suchas first-order logic structures that a computer module can manipulate),machine translation (e.g., automatically translate text from one humanlanguage to another), morphological segmentation (e.g., separating wordsinto individual morphemes and identify the class of the morphemes, whichcan be challenging based on the complexity of the morphology orstructure of the words of the language being considered), questionanswering (e.g., determining an answer to a human-language question,which can be specific or open-ended), semantic processing (e.g.,processing that can occur after identifying a word and encoding itsmeaning in order to relate the identified word to other words withsimilar meanings).

The NLP component 112 converts the audio input signal into recognizedtext by comparing the input signal against a stored, representative setof audio waveforms (e.g., in the data repository 124) and choosing theclosest matches. The set of audio waveforms can be stored in datarepository 124 or other database accessible to the data processingsystem 102. The representative waveforms are generated across a largeset of users, and then may be augmented with speech samples from theuser. After the audio signal is converted into recognized text, the NLPcomponent 112 matches the text to words that are associated, for examplevia training across users or through manual specification, with actionsthat the data processing system 102 can serve.

The audio input signal can be detected by the sensor 134 or transducer136 (e.g., a microphone) of the local client computing device 104. Viathe transducer 136, the audio driver 138, or other components the localclient computing device 104 can provide the audio input signal to thedata processing system 102 (e.g., via the network 105) where it can bereceived (e.g., by the interface 110) and provided to the NLP component112 or stored in the data repository 124.

The NLP component 112 can obtain the input audio signal. From the inputaudio signal, the NLP component 112 can identify at least one request orat least one trigger keyword corresponding to the request. The requestcan indicate intent or subject matter of the input audio signal. Thetrigger keyword can indicate a type of action likely to be taken. Forexample, the NLP component 112 can parse the input audio signal toidentify at least one request to leave home for the evening to attenddinner and a movie. The trigger keyword can include at least one word,phrase, root or partial word, or derivative indicating an action to betaken. For example, the trigger keyword “go” or “to go to” from theinput audio signal can indicate a need for transport. In this example,the input audio signal (or the identified request) does not directlyexpress an intent for transport, however the trigger keyword indicatesthat transport is an ancillary action to at least one other action thatis indicated by the request.

The NLP component 112 can parse the input audio signal to identify,determine, retrieve, or otherwise obtain the request and the triggerkeyword. For instance, the NLP component 112 can apply a semanticprocessing technique to the input audio signal to identify the triggerkeyword or the request. The NLP component 112 can apply the semanticprocessing technique to the input audio signal to identify a triggerphrase that includes one or more trigger keywords, such as a firsttrigger keyword and a second trigger keyword. For example, the inputaudio signal can include the sentence “I need someone to do my laundryand my dry cleaning.” The NLP component 112 can apply a semanticprocessing technique, or other natural language processing technique, tothe data packets comprising the sentence to identify trigger phrases “domy laundry” and “do my dry cleaning”. The NLP component 112 can furtheridentify multiple trigger keywords, such as laundry, and dry cleaning.For example, the NLP component 112 can determine that the trigger phraseincludes the trigger keyword and a second trigger keyword.

The NLP component 112 can filter the input audio signal to identify thetrigger keyword. For example, the data packets carrying the input audiosignal can include “It would be great if I could get someone that couldhelp me go to the airport”, in which case the NLP component 112 canfilter out one or more terms as follows: “it”, “would”, “be”, “great”,“if”, “I”, “could”, “get”, “someone”, “that”, “could”, or “help”. Byfiltering out these terms, the NLP component 112 may more accurately andreliably identify the trigger keywords, such as “go to the airport” anddetermine that this is a request for a taxi or a ride sharing service.

In some cases, the NLP component can determine that the data packetscarrying the input audio signal includes one or more requests. Forexample, the input audio signal can include the sentence “I need someoneto do my laundry and my dry cleaning.” The NLP component 112 candetermine this is a request for a laundry service and a dry cleaningservice. The NLP component 112 can determine this is a single requestfor a service provider that can provide both laundry services and drycleaning services. The NLP component 112 can determine that this is tworequests: a first request for a service provider that performs laundryservices, and a second request for a service provider that provides drycleaning services. In some cases, the NLP component 112 can combine themultiple determined requests into a single request, and transmit thesingle request to a third-party device 146. In some cases, the NLPcomponent 112 can transmit the individual requests to another serviceprovider device, or separately transmit both requests to the samethird-party device 146.

The data processing system 102 can include a direct action API 116designed and constructed to generate, based on the trigger keyword, anaction data structure responsive to the request. Processors of the dataprocessing system 102 can invoke the direct action API 116 to executescripts that generate a data structure to provide to a third-partydevice 146 or other service provider to order a service or product, suchas a car from a car share service. The direct action API 116 can obtaindata from the data repository 124, as well as data received with enduser consent from the local client computing device 104 to determinelocation, time, user accounts, logistical or other information to allowthe third-party device 146 to perform an operation, such as reserve acar from the car share service. Using the direct action API 116, thedata processing system 102 can also communicate with the third-partydevice 146 to complete the conversion by in this example making the carshare pick up reservation.

The direct action API 116 can receive the profile stack constructed bythe stacking engine component 114 for the session. The direct action API116 can apply one or more policies from the profile stack when executinga specified action to satisfy the end user's intention, as determined bythe data processing system 102. Depending on the action specified in itsinputs and the layered profiles and policies in the profile stackconstructed by the stacking engine component 114 for the session, thedirect action API 116 can execute code or a dialog script thatidentifies the parameters required to fulfill a user request. Such codecan look-up additional information, e.g., in the data repository 124,such as the name of a home automation service, or third-party service,or it can provide audio output for rendering at the local clientcomputing device 104 to ask the end user questions such as the intendeddestination of a requested taxi. The direct action API 116 can determineparameters and can package the information into an action datastructure, which can then be sent to another component such as thecontent selector component 118 or to the service provider computingdevice 108 to be fulfilled.

The direct action API 116 can receive an instruction or command from theNLP component 112, or other component of the data processing system 102,to generate or construct the action data structure. The direct actionAPI 116 can determine a type of action in order to select a templatefrom the template repository 122 stored in the data repository 124.Types of actions can include, for example, services, products,reservations, or tickets. Types of actions can further include types ofservices or products. For example, types of services can include carshare service, food delivery service, laundry service, maid service,repair services, household services, device automation services, ormedia streaming services. Types of products can include, for example,clothes, shoes, toys, electronics, computers, books, or jewelry. Typesof reservations can include, for example, dinner reservations or hairsalon appointments. Types of tickets can include, for example, movietickets, sports venue tickets, or flight tickets. In some cases, thetypes of services, products, reservations or tickets can be categorizedbased on price, location, type of shipping, availability, or otherattributes.

The NLP component 112 can parse the input audio signal to identify arequest and a trigger keyword corresponding to the request, and providethe request and trigger keyword to the direction action API 116 to causethe direct action API to generate, based on the trigger keyword and thesecond profile layer pushed to the profile stack data structure, a firstaction data structure responsive to the request that is compatible withthe first profile layer of the profile stack data structure.

The direct action API 116, upon identifying the type of request, canaccess the corresponding template from the template repository 122.Templates can include fields in a structured data set that can bepopulated by the direct action API 116 to further the operation that isrequested via input audio detected by the local computing device 104 ofthe third-party device 146 (such as the operation of sending a taxi topick up an end user at a pickup location and transport the end user to adestination location). The direct action API 116 can perform a lookup inthe template repository 122 to select the template that matches one ormore characteristic of the trigger keyword and request. For example, ifthe request corresponds to a request for a car or ride to a destination,the data processing system 102 can select a car sharing servicetemplate. The car sharing service template can include one or more ofthe following fields: device identifier, pick up location, destinationlocation, number of passengers, or type of service. The direct actionAPI 116 can populate the fields with values. To populate the fields withvalues, the direct action API 116 can ping, poll or otherwise obtaininformation from one or more sensors 134 of the computing device 104 ora user interface of the device 104. For example, the direct action API116 can detect the source location using a location sensor, such as aGPS sensor. The direct action API 116 can obtain further information bysubmitting a survey, prompt, or query to the end of user of thecomputing device 104. The direct action API can submit the survey,prompt, or query via interface 110 of the data processing system 102 anda user interface of the computing device 104 (e.g., audio interface,voice-based user interface, display, or touch screen). Thus, the directaction API 116 can select a template for the action data structure basedon the trigger keyword or the request, populate one or more fields inthe template with information detected by one or more sensors 134 orobtained via a user interface, and generate, create or otherwiseconstruct the action data structure to facilitate performance of anoperation by the third-party device 146.

To construct or generate the action data structure, the data processingsystem 102 can identify one or more fields in the selected template topopulate with values. The fields can be populated with numerical values,character strings, Unicode values, Boolean logic, binary values,hexadecimal values, identifiers, location coordinates, geographic areas,timestamps, or other values. The fields or the data structure itself canbe encrypted or masked to maintain data security.

Upon determining the fields in the template, the data processing system102 can identify the values for the fields to populate the fields of thetemplate to create the action data structure. The data processing system102 can obtain, retrieve, determine or otherwise identify the values forthe fields by performing a look-up or other query operation on the datarepository 124.

In some cases, the data processing system 102 can determine that theinformation or values for the fields are absent from the data repository124. The data processing system 102 can determine that the informationor values stored in the data repository 124 are out-of-date, stale, orotherwise not suitable for the purpose of constructing the action datastructure responsive to the trigger keyword and request identified bythe NLP component 112 (e.g., the location of the local client computingdevice 104 may be the old location and not be the current location; anaccount can be expired; the destination restaurant may have moved to anew location; physical activity information; or mode of transportation).

If the data processing system 102 determines that it does not currentlyhave access, in memory of the data processing system 102, to the valuesor information for the field of the template, the data processing system102 can acquire the values or information. The data processing system102 can acquire or obtain the information by querying or polling one ormore available sensors of the local client computing device 104,prompting the end user of the local client computing device 104 for theinformation, or accessing an online web-based resource using an HTTPprotocol. For example, the data processing system 102 can determine thatit does not have the current location of the local client computingdevice 104, which may be a needed field of the template. The dataprocessing system 102 can query the local client computing device 104for the location information. The data processing system 102 can requestthe local client computing device 104 to provide the locationinformation using one or more location sensors 134, such as a GlobalPositioning System sensor, WIFI triangulation, cell tower triangulation,Bluetooth beacons, IP address, or other location sensing technique.

In some cases, the data processing system 102 can generate the actiondata structure using the second profile. The data processing system 102can then determine whether the action data structure generated using thesecond profile is compliant with the first profile. For example, thefirst profile can include a policy to block a type of action datastructure, such as purchasing a product from an electronic onlineretailer via the local computing device 104. The input audio detected bythe local computing device 104 may have included a request to purchase aproduct from the electronic online retailer. The data processing system102 may have used the second profile to identify account informationassociated with the electronic online retailer, and then generated anaction data structure to purchase the product. The action data structurecan include the account identifier corresponding to the electronicaccount associated with the acoustic signature identified by the speakerrecognition component 120.

Upon generate the action data structure, the direct action API 116 mayattempt to transmit the action data structure to the electronic onlineretailer. However, the stacking engine component 114 can intercept theaction data structure. The stacking engine component 114 can analyze theaction data structure to determine whether it complies with the one ormore policies in the first profile layer in the profile stackestablished for the session. If the stacking engine component 114determines that the action data structure to purchase the product fromthe electronic retailer is compliant, then the stacking engine component114 can release the action data structure. If, however, the stackingengine component determines that the action data structure is contraryto, or not compliant with, the first profile layer, then the stackingengine component 114 can block the action data structure.

In some cases, the direct action API 116 can retrieve the profile stackand identify the first profile layer and the second profile layer, wherethe second profile layer corresponds to a subsequently pushed secondprofile. The direct action API 116 can generate the action datastructure using the last pushed profile, such as the second profile. Thedirect action API 116 can then compare the action data structuregenerated using the second profile with one or more policies containedin the first profile. Based on the comparison using the policies, thedirect action API 116 can determine whether to approve the action datastructure or to block the action data structure.

For example, the data processing system 102 can generate a first actiondata structure based on the trigger keyword and the second profile layerpushed to the profile stack. The data processing system 102 can generatethe first action data structure responsive to the request in the inputaudio signal. The data processing system 102 can compare the firstaction data structure with the one or more policies of the first profilelayer, where the first profile layer corresponds to a default profilelayer or baseline profile layer. The data processing system 102 candetermine, based on a comparison of the first action data structure withthe one or more policies of the first profile layer, that the firstaction data structure is compatible with the first profile layer.Responsive to the first action data structure determined to becompatible with the first profile layer, the data processing system 102can provide the first action data structure for execution.

The policies in the first profile layer can include a policy to block atype of action data structure. Types of action data structure that canbe blocked can include, for example, an action data structure topurchase a product or service from a competitor entity of thethird-party, unsecure action, or network bandwidth intensive actions(e.g., stream 4K resolution multimedia content, download large datafiles, such as over 50 megabytes, 100 megabytes, or more). The dataprocessing system can compare a type of the first action with the typeof action data structure indicated by the one or more policies of thefirst profile layer to determine whether the first action data structureis compatible with the first profile layer. If the first action datastructure is allowed by the policy (e.g., not blocked by the policy),then the data processing system 102 can approve the first action datastructure.

In some cases, the data processing system 102 can receive the triggerkeyword identified by the natural language processor and the profilestack data structure. The data processing system 102 can select, basedon the trigger keyword and the profile stack data structure, a digitalcomponent that is compatible with both the first profile layer and thesecond profile layer. The digital component can refer to a supplementaldigital component. For example, the data processing system 102 caninclude, execute, or otherwise communicate with a content selectorcomponent 118 to receive the trigger keyword identified by the naturallanguage processor and select, based on the trigger keyword, a digitalcomponent via a real-time content selection process. The contentselection process can refer to, or include, selecting sponsored digitalcomponent objects provided by third party content providers 106. Thereal-time content selection process can include a service in whichdigital components provided by multiple content providers are parsed,processed, weighted, or matched in order to select one or more digitalcomponents to provide to the computing device 104. The content selectorcomponent 118 can perform the content selection process in real-time.Performing the content selection process in real-time can refer toperforming the content selection process responsive to the request forcontent received via the local client computing device 104. Thereal-time content selection process can be performed (e.g., initiated orcompleted) within a time interval of receiving the request (e.g., 5seconds, 10 seconds, 20 seconds, 30 seconds, 1 minute, 2 minutes, 3minutes, 5 minutes, 10 minutes, or 20 minutes). The real-time contentselection process can be performed during a communication session withthe local client computing device 104, or within a time interval afterthe communication session is terminated.

For example, the data processing system 102 can include a contentselector component 118 designed, constructed, configured or operationalto select digital component objects. To select digital components fordisplay in a voice-based environment, the data processing system 102(e.g., via NLP component 112) can parse the input audio signal toidentify keywords (e.g., a trigger keyword), and use the keywords toselect a matching digital component based on a broad match, exact match,or phrase match. For example, the content selector component 118 cananalyze, parse, or otherwise process subject matter of candidate digitalcomponents to determine whether the subject matter of the candidatedigital components correspond to the subject matter of the keywords orphrases of the input audio signal detected by the microphone of thelocal client computing device 104. The content selector component 118may identify, analyze, or recognize voice, audio, terms, characters,text, symbols, or images of the candidate digital components using animage processing technique, character recognition technique, naturallanguage processing technique, or database lookup. The candidate digitalcomponents may include metadata indicative of the subject matter of thecandidate digital components, in which case the content selectorcomponent 118 may process the metadata to determine whether the subjectmatter of the candidate digital component corresponds to the input audiosignal.

The content selector component 118 can further utilize informationprovided in the profile stack to perform content selection. The contentselector component 118 can utilize the second profile layer, which cancorrespond to the electronic account associated with the speaker thatprovided the input audio signal detected by the local computing device104. The content selector 118 can also use information associated withthe first profile layer, which can correspond to the default profilelayer that was provided by the third-party device 146. The contentcampaign provided by the content provider 106 can include contentselection criteria that the data processing system 102 can match tocriteria indicated in the second profile layer or the first profilelayer.

The profile layer can alter weights or scores used by the contentselector component 118 to select a digital component. For example, thefirst profile layer established by the third-party device can increasethe weight or score for digital components for or describing products orservices provided by the third-party entity, while lowering the weightor score for products or services provided by a competitor of thethird-party entity. Because the local computing device 104 can belocated in a setting controlled by the third-party entity, thethird-party entity can establish content selection rules, policies, orweighting in the first profile layer that are to be utilized by thecontent selector component 118 during content selection.

By using the second profile layer to select digital components, thecontent selector component 118 can reduce excessive transmissions ofdigital components by more precisely selecting a digital component basedon the second profile layer and not just the first profile layer.Selecting digital components using the profile stack constructed frommultiple profiles, as opposed to just selecting digital components usingthe first layer (or default layer) or just the second layer (the profileassociated with the electronic account) can result in an erroneous orirrelevant digital component selection. The first profile layer canprovide information associated with the third-party entity or the publicor unsecure location at which the local computing device 104 is locatedthat may facilitate content selection, or block an erroneous contentselection. For example, the input audio signal can include a request fordry cleaning service. The content selector component 118 may receive therequest and attempt to identify a supplemental digital componentprovided by a content provider device 106. To identify a supplementalcontent provider, the content selector component 118 can execute areal-time content selection process using one or more characteristicsassociated with the request. The content selector component 118 canfurther input information obtained from the second profile layer. Usingthe information from the second profile layer, the content selectorcomponent 118 may select a digital component corresponding to a drycleaning service provider. However, the first profile layer can includea policy that blocks provision of supplemental digital componentsrelated to dry cleaning service providers because the third-party entitythat established the first profile layer may provide dry cleaningservices that are preferred. The content selector component 118 may nothave selected a digital component for the dry cleaning services providedby the third-party entity because the third-party entity may not haveestablished a content campaign for their own dry cleaning services.Thus, without utilizing the profile stack comprising both the firstprofile layer and the second profile layer, the data processing system102 may have erroneously provided a supplemental digital componentcorresponding to a dry cleaning service provider when the preferringdigital component corresponds to a dry cleaning service provided by thethird-party entity, which is identified in the first profile layer.Thus, the data processing system 102 can overwrite or replace theselected digital component with the preferred digital componentindicated via the first profile layer (or default profile layer).

In some cases, the content selector component 118 can parse the firstprofile layer to determine whether the first profile layer includes apolicy or information that blocks selection of a type of digitalcomponent, and prevent executing the real-time content selectionprocess, thereby reducing the utilization of computing resources as wellas potentially reducing delay or latency in providing a digitalcomponent responsive to the request contained in the input audio signal.

Content providers 106 may provide additional indicators when setting upa content campaign that includes digital components. The contentprovider 106 may provide information at the content campaign or contentgroup level that the content selector component 118 may identify byperforming a lookup using information about the candidate digitalcomponent. For example, the candidate digital component may include aunique identifier, which may map to a content group, content campaign,or content provider. The content selector component 118 may determine,based on information stored in content campaign data structure in datarepository 124, information about the content provider 106.

The data processing system 102 can receive, via a computer network, arequest for content for presentation on a computing device 104. The dataprocessing system 102 can identify the request by processing an inputaudio signal detected by a microphone of the local client computingdevice 104. The request can include selection criteria of the request,such as the device type, location, and a keyword associated with therequest. The request can include the action data structure or actiondata structure.

Responsive to the request, the data processing system 102 can select adigital component object from data repository 124 or a databaseassociated with the content provider 106, and provide the digitalcomponent for presentation via the computing device 104 via network 105.The digital component object can be provided by a content providerdevice 108 different from the third-party device 146. The digitalcomponent can correspond to a type of service different from a type ofservice of the action data structure (e.g., taxi service versus fooddelivery service). The computing device 104 can interact with thedigital component object. The computing device 104 can receive an audioresponse to the digital component. The computing device 104 can receivean indication to select a hyperlink or other button associated with thedigital component object that causes or allows the computing device 104to identify service provider 108, request a service from the serviceprovider 108, instruct the service provider 108 to perform a service,transmit information to the service provider 108, or otherwise query thethird-party device 146.

The data processing system 102 (e.g., via interface 110 and network 105)can transmit data packets comprising the output signal that isresponsive to the input audio signal, or request or query thereof. Theoutput signal can cause the audio driver component 138 of or executed bythe client device 104 to drive a speaker (e.g., transducer 136) of thelocal computing device 104 to generate an acoustic wave corresponding tothe output signal.

The data processing system 102 (e.g., via stacking engine component 114)can disassemble the profile stack data structure to remove one of thefirst profile layer or the second profile layer from the profile stackdata structure. The data processing system can disengage from theelectronic account by reverting back to a previous configuration ordefault configuration, and erasing or protecting all informationassociated with the session and the electronic account. For example, thedata processing system can remove or delete the second profile layerfrom the profile stack data structure configured for the local computingdevice 104. The data processing system 102 can revert or reset the localcomputing device 104 to a factory setting or default configuration. Thedata processing system 102 can upload any session related information tothe second profile stored in the data processing system 102, and removeor purge any local copy of the information associated with the secondprofile.

The data processing system 102 can remove one of the first or secondprofile layers from the profile stack responsive to detection of atrigger event. The trigger event can be based on a time interval,instruction, event, location, geofence, unauthorized use, frauddetection, or new speaker recognition. The data processing system 102can determine to remove one of the first profile or the second profilebased on the type of trigger event.

The data processing system 102 (e.g., via speaker recognition component120) can determine that a different user is providing input audiosignals to the local computing device 104. The different user can be asecond user that that is not the same as the first user. The second usercan have a different acoustic signature. The speaker recognitioncomponent 120 can detect the second acoustic signature, determine thatthere is a different user, and then terminate the session with the firstuser. The speaker recognition component 120 can provide an indication ofthe second, different user to the stacking engine component 114, whichcan remove the second profile layer from the profile stack. The stackingengine component 114, responsive to receiving the indication of thesecond user different from the first user, can clear the profile stackdata structure or just remove the second profile layer corresponding tothe first user.

The data processing system 102 receive, via the interface 110, seconddata packets comprising a second input audio signal detected by thesensor 134 of the client device (e.g., local computing device 104). Thesecond input audio signal can be detected subsequent to the audiosignal. The data processing system 102 (e.g., speaker recognitioncomponent 120) can identify a second acoustic signature from the secondinput audio signal. The second acoustic signature can be different fromthe first acoustic signature. The data processing system 102 candetermine the trigger event based on identification of the secondacoustic signature different from the first acoustic signature

The stacking engine component 114 can clear the profile stack or removethe second profile layer responsive to inactivity for time interval. Thestacking engine component 114 can clear the profile stack or the secondprofile layer responsive to the user corresponding to the second profilelayer not providing any voice input for a time interval, such as 5minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 1hour, or more. Clearing the profile stack or removing the second profilelayer can provide increased security as well as well as maintain aminimal profile stack in memory.

The stacking engine component 114 can clear the profile stack responsiveto determining that the user corresponding to the second profile layerhas left the public location or unsecure location corresponding to thelocal computing device 104 or the third-party entity. The stackingengine component 114 can receive an indication from the mobile computingdevice 144, which can be carried by the user, that the mobile computingdevice 144 is greater than a threshold distance away from the localcomputing device 104. The threshold distance can be 20 meters, 25meters, 50 meters, 100 meters, 200 meters, 500 meters, 750 meters, 1000meters, or more. For example, the stacking engine component 114 canestablish a geographic fence around the local computing device 104. Thegeographic fence can refer to a virtual geographic boundary, defined byGlobal Positioning System (“GPS”) or radio frequency identification(“RFID”) or near field communication beacons, that allows software totrigger a response when a mobile device enters or leaves a particulararea around the local computing device 104. Thus, when a user leaves thehotel room with their mobile computing device 144, the data processingsystem 102 can automatically remove the second profile layer from theprofile stack used to process voice input detected by the localcomputing device 104.

The stacking engine component 114 can interface with the third-partydevice 146 and receive an indication from the third-party device 146 toclear the profile stack or remove the second profile layer. For example,the third-party device 146 can include an electronic hotel guestmanagement system that receive an indication that the user associatedwith the second profile layer has checked out of the hotel room.Responsive to receiving the indication that the guest has checked out,the third-party device 146 can forward the indication to the dataprocessing system 102. The data processing system 102 (e.g., stackingengine component 114) can receive the indication that the guest haschecked out and, responsive to the indication, remove the second profilelayer from the profile stack used to process voice input associated withthe local computing device 104, thereby disassembling the profile stack.

Disassembling the profile stack data structure can include removing orclearing one or more profiles from the profile stack. Disassembling theprofile stack can include removing only the first profile layer,removing only the second profile layer, or removing both the firstprofile layer and the second profile layer. For example, the dataprocessing system can remove the second profile layer that correspondsto the electronic account corresponding to the acoustic signature, whilekeeping the first profile layer corresponding to a default profilelayer.

FIG. 2 is an illustration of the operation of system 100 to process aprofile stack. The system 100 can operate in an environment 200. Theenvironment 200 can include one or more component of system 100 depictedin FIG. 1 or system 600 depicted in FIG. 6. The environment 200 caninclude a secured public location 202. The secured public location 202can refer to a public location. A public location can refer to alocation, place, building, house, room, or other structure or place thatcan be occupied by multiple users at the same time or at differenttimes, or accessed by multiple users. For example, a public place orpublic location can include a hotel room, motel room, guest room, rentalcar, physical retail store, mall, park, office, or cubicle. In thisexample, the secured public location 202 can be a hotel room. The publiclocation 202 can be secured because the mobile computing device 144 maybe located within the location 202, thereby indicating that the user maybe present. However, the system may deem the location 202 to be unsecurebased on a trigger event or time interval without activity, regardlessof whether the mobile computing device 144 is located within thelocation 202.

The hotel room (or secured public location 202) can include severalinternet connected devices, such as a connected telecommunication device204 (e.g., connected telephone), a connected thermostat 206, connectedlamp 208, connected speaker 210 (or sound system), or connectedmultimedia display 212 (or smart television). The internet connecteddevices 204, 206, 208, 210 or 212 can connect to network 105 via awireless gateway 214 (e.g., network router, wireless router, or modem),which can provide access to network 105. The internet connected devices204, 206, 208, 210 or 212 can be monitored, managed, or controlled viadata processing system 102. In some cases, the internet connecteddevices 204, 206, 208, 210 or 212 can be monitored, managed, orcontrolled by the third-party device 146 via the data processing system102.

In the illustrative environment 200 depicted in FIG. 2, the mobilecomputing device 144 is located in the hotel room or secured publiclocation 202. The local computing device 104 is also located in thesecured public location 202. The local computing device 104 can receivevoice input from a user located in the hotel room. The local computingdevice 104 can generate data packets comprising the input audio, andtransmit the data packets to the data processing system 102 via wirelessgateway 214 and network 105. The data processing system 102 can receivethe data packets and perform speaker recognition to identify an acousticsignature from the input audio signal. The data processing system 102can then identify an electronic account corresponding to the acousticsignature. The data processing system 102 can select a profilecorresponding to the electronic account, and then push the profile tothe profile stack data structure 142 for the local computing device 104.The profile stack data structure 142 can be specific to the localcomputing device 104. For example, each local computing device 104 canhave a respective profile stack data structure 142. The profile stackdata structure 142 for the local computing device 104 can be stored ormaintained on the data processing system 102 (e.g., in a data repositoryor memory of the data processing system 102) to facilitate processingusing the profile stack data structure 142. In some cases, the profilestack data structure 142 can be stored locally in memory on the localcomputing device 104.

The profile stack data structure 142 can include a first profile layer“Layer 1” that corresponds to the default profile or baseline profileestablished by the third-party device 146. The third-party device 146can provide the layer 1 profile to the data processing system 102 forplacement in the profile stack data structure 142. The data processingsystem 102, responsive to detecting the acoustic signature, can push asecond profile corresponding to the electronic account to the profilestack data structure 142 for placement in a second profile layer “Layer2”.

The Layer 1 profile can include predetermined labels for the internetconnected devices 204, 206, 208, 210 or 212. The labels can beestablished via the third-party device 146. The third-party device 146can be associated with a third-party entity that manages, owns, oradministrates the secured public location 202 (e.g., hotel).

The second profile layer in Layer 2 can include profile informationassociated with the electronic account of the user corresponding to theacoustic signature. The second profile may or may not include labels forinternet connected devices 204, 206, 208, 210 or 212. In the event thesecond profile includes a label for an internet connected device that issimilar to a label provided in the Layer 1, the data processing system102 can determine to use the Layer 1 label because the labels in Layer 1may be ranked higher or prioritized higher than the labels in Layer 2.In some cases, the data processing system 102 can provide a prompt tothe user to clarify which internet connected device is being referred tofacilitate disambiguation and reduce the number of action datastructures that are transmitted to internet connected devices, therebyreducing network bandwidth utilization as well as computing resourceutilization by the unintended internet connected devices.

For example, the input audio can include a request to “turn on my livingroom lamp”. If the profile stack data structure only included the Layer1 profile, then the data processing system 102 may determine that thelamp corresponds to the connected lamp 208 because there is only oneconnected lamp in the hotel room 202. The data processing system 102 maythen turn on the connected lamp 208 by sending an action data structureincluding an instruction to the connected lamp 208 via the network 105.If, however, there is a Layer 2 profile loaded in the profile stack datastructure 142, the data processing system 102 can parse the secondprofile to determine whether it contains a label “living room lamp”. Thelabel “living room lamp” may correspond to a lamp at a private residenceassociated with the electronic account. If the data processing system102 detects the label “living room lamp”, then the data processingsystem 102 may transmit an action data structure including aninstruction to the connected living room lamp located at the privateresidence.

The local computing device 104 can include an audio driver 138, atransducer 136, a sensor 134 and a pre-processor component 140. Thesensor 134 can receive or detect an input audio signal (e.g., voiceinput). The pre-processor component 140 can be coupled to the audiodriver, the transducer, and the sensor. The pre-processor component 140can filter the input audio signal to create a filtered input audiosignal (e.g., by removing certain frequencies or suppressing noise). Thepre-processor component 140 can convert the filtered input audio signalto data packets (e.g., using a software or hardware digital-to-analogconverter). In some cases, the pre-processor component 140 can convertthe unfiltered input audio signal to data packets and transmit the datapackets to the data processing system 102. The pre-processor component140 can transmit the data packets to a data processing system 102comprising one or more processors and memory that execute a naturallanguage processor component, an interface, a speaker recognitioncomponent, and a direct action application programming interface.

The data processing system 102 can receive, via the interface, from thepre-processor component, the data packets comprising the filtered (orunfiltered) input audio signal detected by the sensor. The dataprocessing system 102 can identify an acoustic signature from the inputaudio signal. The data processing system 102 can identify, based on alookup in a data repository (e.g., querying a database), an electronicaccount corresponding to the acoustic signature. The data processingsystem 102 can establish, responsive to identification of the electronicaccount, a session and a profile stack data structure for use in thesession. The profile stack data structure comprising a first profilelayer having one or more policies configured by a device of athird-party entity. The data processing system 102 can push, to theprofile stack data structure established for the session, a secondprofile layer retrieved from the electronic account. The data processingsystem 102 can parse the input audio signal to identify a request and atrigger keyword corresponding to the request. The data processing system102 can generate, based on the trigger keyword and the second profilelayer pushed to the profile stack data structure, a first action datastructure responsive to the request that is compatible with the firstprofile layer of the profile stack data structure. The data processingsystem 102 can provide the first action data structure for execution.The data processing system 102 can disassemble, responsive to detectionof a trigger event, the profile stack data structure to remove one ofthe first profile layer or the second profile layer from the profilestack data structure.

The data processing system 102 can provide, to the pre-processorcomponent of the local computing device 104, a status of the profilestack data structure. The status can indicate that the second profilelayer has been pushed to the profile stack. The status can indicate thatboth the first profile layer and second profile layer are in the profilestack. The status can indicate that the second profile layer has beenremoved from the profile stack. The status can indicate that the profilestack has been cleared or returned to a default state (e.g., with onlythe first profile layer in the profile stack). Various terms can be usedto indicate the status, including, for example, “secured setting”;“public setting”; “<identifier of electronic account>”; or “ready”.

The local computing device 104 can receive the indication of the status.The audio driver can receive the indication of the status of the profilestack data structure, and generate an output signal based on theindication. The audio driver can convert the indication to an outputsignal, such as sound signal, or acoustic output signal. The audiodriver can drive the transducer 136 (e.g., speaker) to generate soundbased on the output signal generated by the audio drive.

In some cases, the local computing device 104 can include a lightsource. The light source can include one or more LEDs, lights, display,or other component or device configured to provide an optical or visualoutput. The pre-processor component can cause the light source toprovide a visual indication corresponding to the status of the profilestack data structure. For example, the visual indication can be a statusindicator light that turns on, a change in color of the light, a lightpattern with one or more colors, or a visual display of text or images.

FIG. 3 is an illustration of the operation of system 100 to process aprofile stack. The system 100 can operate in an environment 300 caninclude one or more component of system 100 depicted in FIG. 1,environment 200 depicted in FIG. 2, or system 600 depicted in FIG. 6.The environment 300 can include the same location 202 depicted in FIG.2, but the location may not be an unsecured public location 302, asopposed to a secured public location 202. The public location may be anunsecured public location 302 because the mobile computing device 144 islocated outside the secured public location 304. Outside the securedlocation 304 can refer to being outside a geographic fence or furtherthan a distance threshold from the local computing device 104. Theinternet connected devices 204, 206, 208, 210, and 212 inside theunsecured public location 302 can be the same internet connected devicesinside the secured public location 202. However, the mobile computingdevice 144 leaving the location 302 can trigger a termination event thatcauses the data processing system 102 to disassemble the profile stackdata structure 142. Disassembling the profile stack data structure 142can include removing the second profile in the Layer 2, while leavingthe first profile in Layer 1. The data processing system 102 can returnthe profile stack data structure 142 to a default state configured forthe local computing device 104 established by the third-party. Forexample, the data processing system 102 can transmit an instruction 306to remove Layer 2 from the profile stack data structure 142.

FIG. 4 is an illustration of the operation of system 100 to process aprofile stack. The system 100 can operate in an environment 400 caninclude one or more component of system 100 depicted in FIG. 1, orsystem 600 depicted in FIG. 6. The environment 400 can include a securedprivate location 402, such as a private residence corresponding to theuser associated with the electronic account with the acoustic signatureassociated with the second profile. The secured private location 402 caninclude several internet connected devices that can be managed,monitored, or controlled by data processing system 102. The internetconnected devices can include, for example, a connectedtelecommunication device 204, connected thermostat 206, connected lamp208, connected speaker 210, and connected multimedia display 212. Thesecured private location 402 can also include a local computing device104. The local computing device can include one or more component orfunctionality as local computing device 104. The secured privatelocation 402 can also include a wireless gateway 214, which can includeone or more component or functionality as wireless gateway 214 locatedin the public location 202 depicted in FIG. 2.

The connected telecommunication device 204 located in the securedprivate location 402 can include one or more component or functionalityas the connected telecommunication device 204 located in the publiclocation 202 depicted in FIG. 2. However, the connectedtelecommunication device 204 located in the secured private location 402can include different configuration settings or identifiers as comparedto the connected telecommunication device 204 located in the publiclocation 202 depicted in FIG. 2.

The connected thermostat 206 located in the secured private location 402can include one or more component or functionality as the connectedthermostat 206 located in the public location 202 depicted in FIG. 2.However, the connected thermostat 206 located in the secured privatelocation 402 can include different configuration settings or identifiersas compared to the connected thermostat 206 located in the publiclocation 202 depicted in FIG. 2.

The connected lamp 208 located in the secured private location 402 caninclude one or more component or functionality as the connected lamp 208located in the public location 202 depicted in FIG. 2. However, theconnected lamp 208 located in the secured private location 402 caninclude different configuration settings or identifiers as compared tothe connected lamp 208 located in the public location 202 depicted inFIG. 2.

The connected speaker 210 located in the secured private location 402can include one or more component or functionality as the connectedspeaker 210 located in the public location 202 depicted in FIG. 2.However, the connected speaker 210 located in the secured privatelocation 402 can include different configuration settings or identifiersas compared to the connected speaker 210 located in the public location202 depicted in FIG. 2.

The connected multimedia display 212 located in the secured privatelocation 402 can include one or more component or functionality as theconnected multimedia display 212 located in the public location 202depicted in FIG. 2. However, the connected multimedia display 212located in the secured private location 402 can include differentconfiguration settings or identifiers as compared to the connectedmultimedia display 212 located in the public location 202 depicted inFIG. 2.

The secured private location 402 can refer to a private residence, homeor apartment of the user. The local computing device 104 in the securedprivate location 402 may not utilize a default or baseline profileprovided by a third-party device 146. Thus, the data processing system102 can add only a Layer 2 profile associated with the second user'selectronic account. The profile stack data structure 142 (which caninclude one or more component or functionality of profile stack datastructure 142) for the local computing device 104 located at the securedprivate location 402 may not include a Layer 1 profile established by athird-party device. Thus, the data processing system 102 can only addLayer 2 404 to the profile stack data structure 142.

However, should a second user enter the secured private location 402 andprovide a voice input that is detected by the local computing device104, the data processing system 102 can select a third profilecorresponding to the second user, and then push the third profile to theprofile stack data structure 142 as a Layer 3 (where there is no Layer 1depicted to illustrate a layering structure consistent with profilestack data structure 142).

In some cases, the local computing device 104 and the data processingsystem 102 in the secured private location 402 can push one or moreadditional profile layers on to the profile stack data structure 142.For example, a guest at the secure private location 402 can providevoice input that can be detected by the local computing device 104. Thelocal computing device 104, upon detecting the voice input or inputaudio signal, can perform pre-processing on the input audio signal andtransmit data packets corresponding to the input audio signal to thedata processing system 102 for further processing. The data processingsystem 102 can attempt to detect an acoustic signature from the inputaudio signal. The data processing system 102 may identify the acousticsignature and then attempt to identify a corresponding electronicaccount for the guest. However, the data processing system 102 may notbe able to identify a corresponding electronic account for the guest—orthe data processing system 102 may not be able to identify an acousticsignature. In either case, the data processing system 102 may not haveaccess to or be able to select a profile layer responsive to the inputaudio signal or acoustic signature thereof. In this case, the dataprocessing system 102 can utilize a separate processing flow.

For example, a guest user that provided the input audio signal may nothave an electronic account or profile established with the dataprocessing system 102. The guest may have a mobile computing device 144.The data processing system 102 can determine the absence of theelectronic account corresponding to the input audio signal. In somecases, the data processing system 102 can generate a prompt or requestto create a new profile. However, if the guest user rejects the promptor request to create a new profile, or in the event the data processingsystem 102 determines to proceed with the processing flow withoutcreating a profile, the data processing system 102 can initiate aprofile-less flow or enter a guest-mode. In the guest-mode, the dataprocessing system 102 can utilize separate authentication mechanism. Forexample, the data processing system 102 can, via a display devicecoupled to the local computing device 104, present an optic code such asa QR code (or some other code, such as a unique identifier of anaccount, identifier or a financial instrument). The unique identifier orQR code can allow the guest to establish a temporary session that doesnot result in the creation of a profile or an electronic account. Thedata processing system 102 can proceed with constructing an action datastructure or performing other tasks via the temporary session.

In some cases, the data processing system 102 may transmit a digitalcomponent to purchase a product, such as the local computing device 104itself, to the mobile computing device 144 of the guest.

FIG. 5 is an illustration of a method of processing stacked datastructures via a computer network. The method 500 can be performed byone or more component, system or element of system 100 depicted in FIG.1, or system 600 depicted in FIG. 6. The method 500 can be performed inenvironment 200 depicted in FIG. 2, environment 300 depicted in FIG. 3,or environment 400 depicted in FIG. 4. The method 500 can include a dataprocessing system receiving an input audio signal at ACT 502. The dataprocessing system receive the data packets including the input audiosignal via an interface. The input audio signal may have been detectedby a sensor of a local computing device, such as a microphone. The localcomputing device may be located in a public location, such as a hotel.In some cases, the local computing device may be located in a secure,private location, such as a residence. The local computing device candetect voice input, pre-process the voice input, generate data packetscomprising at least some of the voice input, and transmit the datapackets to the data processing system. The local computing device maytransmit the data packets responsive to identifying a trigger keywordthat indicates to the local computing device to detect the voice input,convert it to digital data packets, and transmit the digital datapackets to the data processing system for further processing.

At ACT 504, the data processing system identifies a signature. The dataprocessing system can identify an acoustic signature from the inputaudio signal. The data processing system can apply speaker recognitiontechniques, pattern recognition or other techniques to identify theacoustic signature. The data processing system can identify one or moreacoustic signatures. In some cases, the data processing system canprompt the user for multi-factor authentication, such as via a passcode,password, pin, passphrase, other biometric authentication, or securitycode transmitted to a mobile device.

At ACT 506, the data processing system identifies an account. The dataprocessing system can perform a lookup in a data repository sing theacoustic signature to identify an electronic account. The dataprocessing system can perform the lookup responsive to authenticationbased on the acoustic signature, or multi-factor authentication beingsatisfied. The electronic account can include profile information, suchas preferences, labels, policies, rules, or other information that canreduce erroneous or wasted remote procedure calls, or datatransmissions.

In some cases, the data processing system can identify the accountwithout using the acoustic signature. The data processing system canidentify the account using various input, sensors, or interfaces. Forexample, rather than use the acoustic signature to identify the account,the data processing system can identify the account based on a mobiledevice in the possession of the user. The mobile device can communicateor interact with the local computing device. The user can log intomobile device using the account. Logging into the mobile device usingthe account can refer to inputting credentials such as a username (orother account identifier) and password (or other token, key or biometricpassword) into a software application or operating system executing onthe mobile device, and authenticating the credentials. The mobile devicecan communicate the account information (e.g., username) to the localcomputing device and indicate that the account has been authenticated onthe mobile device. The local computing device can transmit, to the dataprocessing system, an indication of the account identifier and that theaccount identifier has been authenticated or validated. The dataprocessing system can receive the account identifier from the localcomputing device, access the corresponding electronic account, andretrieve the corresponding profile. Thus, the data processing system canidentify an account associated with the user using one or moretechniques that may or may not include using an acoustic signature.Other techniques can include using an optical code (e.g., a quickreference code), biometric (e.g., fingerprint, iris scanner, or facialrecognition), using a keyboard, mouse or touch interface to type anaccount identifier, or using voice input to provide the accountidentifier.

At ACT 508, the data processing system establishes a session and aprofile stack. The data processing system can establish a session and aprofile stack data structure for use in the session. The data processingsystem can establish the session and profile stack data structureresponsive to identification of the electronic account or completion ofan authentication procedure (e.g., acoustic signature-basedauthentication, or multi-factor authentication, or additional biometricauthentication). Since the profile stack data structure can be for thelocal computing device located in the public location maintained by athird-party, the profile stack data structure can include a firstprofile layer having one or more policies configured by a device of thethird-party entity (e.g., hotel administrator, mall administrator, orrental car administrator).

At ACT 510, the data processing system pushes a second profile. The dataprocessing system can push the second profile as a second profile layeronto the profile stack data structure that is established for thesession. The first profile layer may have certain labels or policiesthat take priority over the second profile layer. While the secondprofile layer may be utilized to select digital components and generateaction data structures, the first profile layer can block certain typesof digital components or action data structure from being executed(e.g., delivered for presentation to the user, transmitted to theintended internet connected device, or transmitted to a service providersuch as a ride sharing service).

At ACT 512, the data processing system identifies a request. The dataprocessing system can parse the input audio signal to identify a requestand a trigger keyword corresponding to the request. The data processingsystem can parse the same input audio signal used to identify theacoustic signature, electronic account, and second profile. In somecases, the data processing system may process a second input audiosignal received subsequent to the first input audio signal used toidentify the electronic account and profile. The data processing systemmay identify the request and trigger keyword in the second input audiosignal.

At ACT 514, the data processing system generates and provides an actiondata structure. The data processing system can generate the action datastructure based on the request, trigger keyword and the second profilelayer pushed to the profile stack data structure. The action datastructure can be generated responsive to the request. The action datastructure can be compatible with the first profile layer of the profilestack data structure. While the action data structure can be generatedusing the second profile associated with the electronic accountassociated with the acoustic signature, the data processing system canperform an error check to determine whether the generated action datastructure is compatible or compliant with the first profile layer. Forexample, the first profile layer may block, prevent, or prohibit certaintypes of action data structures that may be erroneous, or consumeexcessive network bandwidth or computing resources.

Upon determining that the action data structure is compliant with thefirst profile layer, the data processing system can provide the firstaction data structure for execution. Providing the action data structurefor execution can include transmitting the action data structure to aninternet connected device to perform the action or provide theinstruction; transmitting the action data structure to a serviceprovider; or providing the action data structure to a content selectorcomponent to receive a digital component.

At ACT 516, the data processing system disassembles the profile stack514. The data processing system can disassemble the profile stackresponsive to detection of a trigger event. The data processing systemcan disassemble the profile stack data structure by removing one of thefirst profile layer or the second profile layer from the profile stackdata structure. For example, the data processing system can reset theprofile stack to the default setting by removing the second profilecorresponding to the acoustic signature. The trigger event can include atime interval (e.g., a custom time interval set by the user, or apredetermined time interval such as 10 minutes, 20 minutes, 30 minutes,1 hour, 12 hours, or 24 hours). The trigger event can include geographicfence, or detection of a second user different from the first user.

By using the profile stack data structure, the data processing systemcan facilitate disambiguating commands received by the local computingdevice. For example, the data processing system can receive a commandwith a grammar “lights at home”. The data processing system can checkthe second profile to identify the one or more internet connecteddevices corresponding to “lights at home”. However, the first profilelayer can also include a label corresponding to “lights at home”. Thedata processing system can provide a prompt to the user to decipherwhich internet connected device are to be controlled. For example, thedata processing system can generate an action data structure based onthe second profile, and then compare the action data structure with apolicy or rule in the first profile to determine whether the generatedaction data structure is compliant with the first profile. In somecases, the data processing system can determine the action datastructure is not compliant because the label overlaps with a label inthe first profile, and, accordingly, block transmission or execution ofthe action data structure without a further prompt.

FIG. 6 is a block diagram of an example computer system 600. Thecomputer system or computing device 600 can include or be used toimplement the system 100, or its components such as the data processingsystem 102. The data processing system 102 can include an intelligentpersonal assistant or voice-based digital assistant. The computingsystem 600 includes a bus 605 or other communication component forcommunicating information and a processor 610 or processing circuitcoupled to the bus 605 for processing information. The computing system600 can also include one or more processors 610 or processing circuitscoupled to the bus for processing information. The computing system 600also includes main memory 615, such as a random access memory (RAM) orother dynamic storage device, coupled to the bus 605 for storinginformation, and instructions to be executed by the processor 610. Themain memory 615 can be or include the data repository 145. The mainmemory 615 can also be used for storing position information, temporaryvariables, or other intermediate information during execution ofinstructions by the processor 610. The computing system 600 may furtherinclude a read only memory (ROM) 620 or other static storage devicecoupled to the bus 605 for storing static information and instructionsfor the processor 610. A storage device 625, such as a solid statedevice, magnetic disk or optical disk, can be coupled to the bus 605 topersistently store information and instructions. The storage device 625can include or be part of the data repository 145.

The computing system 600 may be coupled via the bus 605 to a display635, such as a liquid crystal display, or active matrix display, fordisplaying information to a user. An input device 630, such as akeyboard including alphanumeric and other keys, may be coupled to thebus 605 for communicating information and command selections to theprocessor 610. The input device 630 can include a touch screen display635. The input device 630 can also include a cursor control, such as amouse, a trackball, or cursor direction keys, for communicatingdirection information and command selections to the processor 610 andfor controlling cursor movement on the display 635. The display 635 canbe part of the data processing system 102, the client computing device150 or other component of FIG. 1, for example.

The processes, systems and methods described herein can be implementedby the computing system 600 in response to the processor 610 executingan arrangement of instructions contained in main memory 615. Suchinstructions can be read into main memory 615 from anothercomputer-readable medium, such as the storage device 625. Execution ofthe arrangement of instructions contained in main memory 615 causes thecomputing system 600 to perform the illustrative processes describedherein. One or more processors in a multi-processing arrangement mayalso be employed to execute the instructions contained in main memory615. Hard-wired circuitry can be used in place of or in combination withsoftware instructions together with the systems and methods describedherein. Systems and methods described herein are not limited to anyspecific combination of hardware circuitry and software.

Although an example computing system has been described in FIG. 6, thesubject matter including the operations described in this specificationcan be implemented in other types of digital electronic circuitry, or incomputer software, firmware, or hardware, including the structuresdisclosed in this specification and their structural equivalents, or incombinations of one or more of them.

For situations in which the systems discussed herein collect personalinformation about users, or may make use of personal information, theusers may be provided with an opportunity to control whether programs orfeatures that may collect personal information (e.g., information abouta user's social network, social actions or activities, a user'spreferences, or a user's location), or to control whether or how toreceive content from a content server or other data processing systemthat may be more relevant to the user. In addition, certain data may beanonymized in one or more ways before it is stored or used, so thatpersonally identifiable information is removed when generatingparameters. For example, a user's identity may be anonymized so that nopersonally identifiable information can be determined for the user, or auser's geographic location may be generalized where location informationis obtained (such as to a city, postal code, or state level), so that aparticular location of a user cannot be determined. Thus, the user mayhave control over how information is collected about him or her and usedby the content server.

The subject matter and the operations described in this specificationcan be implemented in digital electronic circuitry, or in computersoftware, firmware, or hardware, including the structures disclosed inthis specification and their structural equivalents, or in combinationsof one or more of them. The subject matter described in thisspecification can be implemented as one or more computer programs, e.g.,one or more circuits of computer program instructions, encoded on one ormore computer storage media for execution by, or to control theoperation of, data processing apparatuses. Alternatively or in addition,the program instructions can be encoded on an artificially generatedpropagated signal, e.g., a machine-generated electrical, optical, orelectromagnetic signal that is generated to encode information fortransmission to suitable receiver apparatus for execution by a dataprocessing apparatus. A computer storage medium can be, or be includedin, a computer-readable storage device, a computer-readable storagesubstrate, a random or serial access memory array or device, or acombination of one or more of them. While a computer storage medium isnot a propagated signal, a computer storage medium can be a source ordestination of computer program instructions encoded in an artificiallygenerated propagated signal. The computer storage medium can also be, orbe included in, one or more separate components or media (e.g., multipleCDs, disks, or other storage devices). The operations described in thisspecification can be implemented as operations performed by a dataprocessing apparatus on data stored on one or more computer-readablestorage devices or received from other sources.

The terms “data processing system” “computing device” “component” or“data processing apparatus” encompass various apparatuses, devices, andmachines for processing data, including by way of example a programmableprocessor, a computer, a system on a chip, or multiple ones, orcombinations of the foregoing. The apparatus can include special purposelogic circuitry, e.g., an FPGA (field programmable gate array) or anASIC (application specific integrated circuit). The apparatus can alsoinclude, in addition to hardware, code that creates an executionenvironment for the computer program in question, e.g., code thatconstitutes processor firmware, a protocol stack, a database managementsystem, an operating system, a cross-platform runtime environment, avirtual machine, or a combination of one or more of them. The apparatusand execution environment can realize various different computing modelinfrastructures, such as web services, distributed computing and gridcomputing infrastructures. For example, the direct action API 116,content selector component 118, or NLP component 112 and other dataprocessing system 102 components can include or share one or more dataprocessing apparatuses, systems, computing devices, or processors.

A computer program (also known as a program, software, softwareapplication, app, script, or code) can be written in any form ofprogramming language, including compiled or interpreted languages,declarative or procedural languages, and can be deployed in any form,including as a stand-alone program or as a module, component,subroutine, object, or other unit suitable for use in a computingenvironment. A computer program can correspond to a file in a filesystem. A computer program can be stored in a portion of a file thatholds other programs or data (e.g., one or more scripts stored in amarkup language document), in a single file dedicated to the program inquestion, or in multiple coordinated files (e.g., files that store oneor more modules, sub programs, or portions of code). A computer programcan be deployed to be executed on one computer or on multiple computersthat are located at one site or distributed across multiple sites andinterconnected by a communication network.

The processes and logic flows described in this specification can beperformed by one or more programmable processors executing one or morecomputer programs (e.g., components of the data processing system 102)to perform actions by operating on input data and generating output. Theprocesses and logic flows can also be performed by, and apparatuses canalso be implemented as, special purpose logic circuitry, e.g., an FPGA(field programmable gate array) or an ASIC (application specificintegrated circuit). Devices suitable for storing computer programinstructions and data include all forms of non-volatile memory, mediaand memory devices, including by way of example semiconductor memorydevices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks,e.g., internal hard disks or removable disks; magneto optical disks; andCD ROM and DVD-ROM disks. The processor and the memory can besupplemented by, or incorporated in, special purpose logic circuitry.

The subject matter described herein can be implemented in a computingsystem that includes a back end component, e.g., as a data server, orthat includes a middleware component, e.g., an application server, orthat includes a front end component, e.g., a client computer having agraphical user interface or a web browser through which a user caninteract with an implementation of the subject matter described in thisspecification, or a combination of one or more such back end,middleware, or front end components. The components of the system can beinterconnected by any form or medium of digital data communication,e.g., a communication network. Examples of communication networksinclude a local area network (“LAN”) and a wide area network (“WAN”), aninter-network (e.g., the Internet), and peer-to-peer networks (e.g., adhoc peer-to-peer networks).

The computing system such as system 100 or system 600 can includeclients and servers. A client and server are generally remote from eachother and typically interact through a communication network (e.g., thenetwork 105). The relationship of client and server arises by virtue ofcomputer programs running on the respective computers and having aclient-server relationship to each other. In some implementations, aserver transmits data (e.g., data packets representing a digitalcomponent) to a client device (e.g., for purposes of displaying data toand receiving user input from a user interacting with the clientdevice). Data generated at the client device (e.g., a result of the userinteraction) can be received from the client device at the server (e.g.,received by the data processing system 102 from the local computingdevice 104 or the content provider computing device 106 or thethird-party device 146).

While operations are depicted in the drawings in a particular order,such operations are not required to be performed in the particular ordershown or in sequential order, and all illustrated operations are notrequired to be performed. Actions described herein can be performed in adifferent order.

The separation of various system components does not require separationin all implementations, and the described program components can beincluded in a single hardware or software product. For example, the NLPcomponent 112 or the content selector component 118, can be a singlecomponent, app, or program, or a logic device having one or moreprocessing circuits, or part of one or more servers of the dataprocessing system 102.
